<h2>SPARQL</h2>
<p>ARQ is an implementation of the
<a href="http://www.w3.org/TR/rdf-sparql-query/">SPARQL query language</a> for Jena.&nbsp;
<a href="http://openjena.org/ARQ/documentation.html">Documentation</a>. </p>

<h2>Persistence Subsystems for Jena</h2>
<p>There are two subsystems for persisting RDF and OWL data,
<a href="http://openjena.org/SDB">SDB</a> or <a href="http://openjena.org/TDB">TDB</a>. 
These are separate downloads. </p>
<p>TDB is a high-performance, native persistence engine using custom indexing 
and storage. SDB is a persistence layer that uses an SQL database and supports 
full ACID transactions. TDB is faster and simpler to setup.</p>

	<li><a href="http://openjena.org/wiki/SDB">SDB documentation</a></li>
</ul>
<p>The original RDB system is still shipped with Jena for legacy applications. 
It is deprecated for new development.</p>
